Swift3.0 Alamofire网络请求的封装（get,post,upload图片上传）

//使用Alamofire进行网络请求时，调用该方法的参数都是通过getRequest(urlString， params, success :, failture :）传入的，而success传入的其实是一个接受           [String : AnyObject]类型 返回void类型的函数

Alamofire.request(urlString, method: .get, parameters: params)
.responseJSON { (response) in/*这里使用了闭包*/
//当请求后response是我们自定义的，这个变量用于接受服务器响应的信息
//使用switch判断请求是否成功，也就是response的result
switch response.result {
case .success(let value):
//当响应成功是，使用临时变量value接受服务器返回的信息并判断是否为[String: AnyObject]类型 如果是那么将其传给其定义方法中的success
//                    if let value = response.result.value as? [String: AnyObject] {
success(value as! [String : AnyObject])
//                    }
